local_irq_save() should be a macro, not a function
because local_irq_save() saves flag to the given argument.
GCC is silent about this issue, but Clang warns:
In file included from lib/asm-offsets.c:15:
In file included from include/common.h:20:
In file included from include/linux/bitops.h:110:
arch/sandbox/include/asm/bitops.h:59:17:
warning: variable 'flags' is uninitialized when used here
[-Wuninitialized]
local_irq_save(flags);
^~~~~
That change causes another warning:
In file included from include/linux/bitops.h:110:0,
from include/common.h:20,
from lib/asm-offsets.c:15:
arch/sandbox/include/asm/bitops.h: In function ‘test_and_set_bit’:
arch/sandbox/include/asm/bitops.h:56:16: warning: unused variable ‘flags’ [-Wunused-variable]
So, flags should be set to __always_unused.
